Upgrade to OnionShare 2.6+, take 2
In %Tails_6.0 we had to revert (!1375 (merged)) to the version from Bullseye due to #20135 (closed) and to a lesser degree #20140 (closed).
That's not ideal.
Ideally we want to get OnionShare 2.6+ working in Debian Bookworm (+ backports), potentially coordinating with the OnionShare upstream. (cc @hefee, @nodens)
But if this is not resolved on the medium-term we need to check if bin/needed-package-updates
handles this situation properly (e.g. will it detect if one of the forward-ported packages has a security update in Bullseye?)
